ordering image and text in jbutton


I am attempting to overlay the text on a JButton over an ImageIcon that is behind it. However, when the imageIcon is added, the text dissapears. Is there any way to specify the order in which it displays? Below, i have tried to separately add the images and text to see if that would affect it, but no luck. Can anyone help me out?

private void initButtons() {

    int locationX = 0, locationY = 525;

    for (int y = 0; y < 8; y++) {
        for (int x = 0; x < 8; x++) {
            boardArray[x][y] = new ChessButton();
            boardArray[x][y].setSize(75, 75);
            boardArray[x][y].setLocation(locationX, locationY);
            boardArray[x][y].setXAndY(x, y);

            if ((x % 2 == 0 && y % 2 == 1) || (x % 2 == 1 && y % 2 == 0)) {
                boardArray[x][y].setColour("white");
                boardArray[x][y].setIcon(new ImageIcon("Assets/white_null_null.png"));

            } else {

                boardArray[x][y].setColour("black");
                boardArray[x][y].setIcon(new ImageIcon("Assets/black_null_null.png"));

            }
//this adds the images in an alternating pattern

            chessFrame.add(boardArray[x][y]);
            locationX = locationX + 75;

        }
        locationX = 0;

        locationY = locationY - 75;

    }

}

void initPieces() {
    for (int y = 0; y < 8; y++) {
        for (int x = 0; x < 8; x++) {

            if ((x % 2 == 0 && y % 2 == 1) || (x % 2 == 1 && y % 2 == 0)) {
                boardArray[x][y].setFont(new Font("Arial Unicode MS", Font.PLAIN, 40));
                boardArray[x][y].setText("\u2654");//sets a particular chess piece as text, just testing it now.

            } else {

                boardArray[x][y].setFont(new Font("Arial Unicode MS", Font.PLAIN, 40));
                boardArray[x][y].setText("\u2654");//sets a particular chess piece as text, just testing it now.
//this is suposed to overlay the image over the text, but it is not.
            }

        }
    }
}

Solution

  • First of all, I see you're calling this method: boardArray[x][y].setLocation(locationX, locationY);

    .setLocation(...) indicates you're using a null layout, please read Null layout is evil and Why is it frowned upon to use a null layout in Swing? to know why you should avoid its use.

    For creating a Chess board, I'd be using GridLayout, please read how to use the different layout managers

    Now, to overlay text over the icon, you only need to call JButton#setHorizontalAlignment(...) method and pass SwingConstants.CENTER as the parameter.

    For example:

    import java.awt.Color;
    import java.awt.Font;
    import java.io.IOException;
    
    import javax.imageio.ImageIO;
    import javax.swing.Icon;
    import javax.swing.ImageIcon;
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.SwingConstants;
    import javax.swing.SwingUtilities;
    
    public class ButtonWithImageAndText {
        private JFrame frame;
        private JButton button;
        private Icon icon;
    
        public static void main(String[] args) {
            SwingUtilities.invokeLater(() -> new ButtonWithImageAndText().createAndShowGui());
        }
    
        private void createAndShowGui() {
            frame = new JFrame(getClass().getSimpleName());
            try {
                icon = new ImageIcon(ImageIO.read(getClass().getResource("up.jpg")));
            } catch (IOException e) {
                e.printStackTrace();
            }
            button = new JButton();
    
            button.setIcon(icon);
    
            button.setText("Click me!");
            button.setHorizontalTextPosition(SwingConstants.CENTER);
            button.setFont(new Font("Arial", Font.PLAIN, 40));
            button.setForeground(Color.RED);
    
            frame.add(button);
            frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frame.pack();
            frame.setVisible(true);
        }
    }
    

    Which gives the following output:
